ʻO EPDM O-ring kahi ʻano sila i hana ʻia mai ka ethylene propylene diene monomer (EPDM) rubber.He kūpaʻa maikaʻi loa ia i nā wela wela, nā kukui UV, a me nā kemika koʻikoʻi, e kūpono ana ia no ka nui o nā noi sila.Loaʻa i nā EPDM O-rings maikaʻi nā waiwai insulation uila a ʻoi aku ka maikaʻi o ke kumukūʻai i hoʻohālikelike ʻia me nā elastomers ʻē aʻe.Hoʻohana pinepine ʻia lākou i nā noi e like me ka mālama ʻana i ka wai, nā panela solar, a me ka hana ʻai.Loaʻa nā EPDM O-rings i nā nui like ʻole a hiki ke hoʻopili ʻia e hoʻokō i nā koi hoʻopaʻa kikoʻī.
